[I.E. Titan]

I was wonder if the fluctuation is normal. I know it does it from time to time but recently I have been worrying.

Normal. Early Titans really fluctuate. I think in 08 Nissan changed the sender for a more graduated response.

Yep, like Krh2 said, the early Titans have a real time oil pressure gauge. So if you step on the gas, your pressure will increase. When my engine is cold, I can easily get it up past the 3/4 mark because the oil is so thick. Once it warms up, it doesn't fluctuate much.

In 08, they started using dummy gauges that basically don't move unless something is wrong.
